e) 

Always use undamaged wheel flanges that are 

of correct size and shape for your selected wheel.

Proper wheel flanges support the wheel thus 
reducing the possibility of wheel breakage. Flanges 
for cut-off wheels may be different from grinding 
wheel flanges.
f) 

Do not use worn down wheels from larger 

power tools.

 Wheel intended for larger power tool is 

not suitable for the higher speed of a smaller tool and 
may burst.

Additional Safety Warnings Specific for Abrasive 
Cutting-Off Operations:

a) 

Do not “jam” the cut-off wheel or apply 

excessive pressure. Do not attempt to make an 
excessive depth of cut.

 Overstressing the wheel 

increases the loading and susceptibility to twisting or 
binding of the wheel in the cut and the possibility of 
kickback or wheel breakage.
b) 

Do not position your body in line with and 

behind the rotating wheel.

 When the wheel, at the 

point of operation, is moving away from your body, 
the possible kickback may propel the spinning wheel 
and the power tool directly at you.
c) 

When wheel is binding or when interrupting a 

cut for any reason, switch off the power tool and 
hold the power tool motionless until the wheel 
comes to a complete stop. Never attempt to 
remove the cut-off wheel from the cut while the 
wheel is in motion otherwise kickback may occur.

Investigate and take corrective action to eliminate the 
cause of wheel binding.
d) 

Do not restart the cutting operation in the 

workpiece. Let the wheel reach full speed and 
carefully re-enter the cut.

 The wheel may bind, walk 

up or kickback if the power tool is restarted in the 
workpiece.
e) 

Support panels or any oversized workpiece to 

minimize the risk of wheel pinching and kickback. 

Large workpieces tend to sag under their own weight. 
Supports must be placed under the workpiece near 
the line of cut and near the edge of the workpiece on 
both sides of the wheel.
f) 

Use extra caution when making a “pocket cut” 

into existing walls or other blind areas.

 The 

protruding wheel may cut gas or water pipes, 
electrical wiring or objects that can cause kickback.

Safety Warnings Specific for Sanding Operations:

a) 

Do not use excessively oversized sanding disc 

paper. Follow manufacturers recommendations, 
when selecting sanding paper.

 Larger sanding 

paper extending beyond the sanding pad presents a 
laceration hazard and may cause snagging, tearing 
of the disc or kickback.

Safety Warnings Specific for Wire Brushing 
Operations:

a) 

Be aware that wire bristles are thrown by the 

brush even during ordinary operation. Do not 
overstress the wires by applying excessive load 
to the brush. 

The wire bristles can easily penetrate 

light clothing and/or skin.
b) 

If the use of a guard is recommended for wire 

brushing, do not allow interference of the wire 
wheel or brush with the guard.

 Wire wheel or brush 

may expand in diameter due to work load and 
centrifugal forces.

Additional Safety Warnings:

16.

When using depressed centre grinding wheels, be 
sure to use only fiberglass-reinforced wheels.

17.

NEVER USE Stone Cup type wheels with this 
grinder.

 This grinder is not designed for these types of 

wheels and the use of such a product may result in 
serious personal injury.

18.

Be careful not to damage the spindle, the flange 
(especially the installing surface) or the lock nut. 
Damage to these parts could result in wheel 
breakage.

19.

Make sure the wheel is not contacting the 
workpiece before the switch is turned on.

20.

Before using the tool on an actual workpiece, let it 
run for a while. Watch for vibration or wobbling 
that could indicate poor installation or a poorly 
balanced wheel.

21.

Use the specified surface of the wheel to perform 
the grinding.

22.

Do not leave the tool running. Operate the tool 
only when hand-held.

23.

Do not touch the workpiece immediately after 
operation; it may be extremely hot and could burn 
your skin.

24.

Observe the instructions of the manufacturer for 
correct mounting and use of wheels. Handle and 
store wheels with care.

25.

Do not use separate reducing bushings or 
adaptors to adapt large hole abrasive wheels.

26.

Use only flanges specified for this tool.

27.

For tools intended to be fitted with threaded hole 
wheel, ensure that the thread in the wheel is long 
enough to accept the spindle length.

28.

Check that the workpiece is properly supported.

29.

Pay attention that the wheel continues to rotate 
after the tool is switched off.

30.

If working place is extremely hot and humid, or 
badly polluted by conductive dust, use a short-
circuit breaker (30 mA) to assure operator safety.

31.

Do not use the tool on any materials containing 
asbestos.

32.

When use cut-off wheel, always work with the dust 
collecting wheel guard required by domestic 
regulation.

33.

Cutting discs must not be subjected to any lateral 
pressure.

SAVE THESE INSTRUCTIONS.

 WARNING:

DO NOT let comfort or familiarity with product (gained 
from repeated use) replace strict adherence to safety 
rules for the subject product. MISUSE or failure to 
follow the safety rules stated in this instruction 
manual may cause serious personal injury.
